The original cast & validation API has been deprecated and replaced with an API that was introduced in 3.2.0.
Using the old API will now result in compiler and runtime warnings.
Old API:
```elixir
defmodule PhoenixAppWeb.UserController do
use PhoenixAppWeb, :controller
plug OpenApiSpex.Plug.Cast
plug OpenApiSpex.Plug.Validate
end
```
Will result in:
```
warning: OpenApiSpex.Plug.Cast.call/2 is deprecated. Use OpenApiSpex.Plug.CastAndValidate instead
test/support/user_controller.ex:1
warning: OpenApiSpex.Plug.Validate.call/2 is deprecated. Use OpenApiSpex.Plug.CastAndValidate.call/2 instead
test/support/user_controller.ex:1
```
New API
```elixir
defmodule PhoenixAppWeb.UserController do
use PhoenixAppWeb, :controller
plug OpenApiSpex.Plug.CastAndValidate, json_render_error_v2: true
end
```
Note that this changes the default error response. Before, it was a single, plain-text error message.
Now, it's a list of error maps, containing more error information.
Old API:
```elixir
defmodule MyAppWeb.MyControllerTest do
use MyApp.ConnCase
# Old module
import OpenApiSpex.Test.Assertions
## The test themselves don't need to change
test "UserController produces a UsersResponse", %{conn: conn} do
api_spec = MyApp.ApiSpec.spec()
json =
conn
|> get(user_path(conn, :index))
|> json_response(200)
assert_schema(json, "UsersResponse", api_spec)
end
test "something" do
api_spec = MyApp.ApiSpec.spec()
schema = MyApp.Schemas.UsersResponse.schema()
assert_schema(schema.example, "UsersResponse", api_spec)
end
end
```
Will produce:
```
warning: OpenApiSpex.Test.Assertions.assert_schema/3 is deprecated. Use OpenApiSpex.TestAssertions.assert_schema/3 instead
test/my_controller_test.exs:21
```
New API:
```elixir
defmodule MyAppWeb.MyControllerTest do
use MyApp.ConnCase
# New module
import OpenApiSpex.TestAssertions
# The test themselves don't need to change,
# but the new assertion is more discerning,
# so it may find problems that the old API didn't.
end
```
## v3.4.0 - 2019-06-14
Thanks to the contributions of the community ❤️💙💛💜🧡
- [surik](https://github.com/surik)
- [holsee](https://github.com/holsee)
- [fmcgeough](https://github.com/fmcgeough)
* Feature: the `OpenApiSpex` and `OpenApiSpex.Info` structs now support [extensions](https://swagger.io/docs/specification/openapi-extensions/) (#108) (#114)
The `extensions` key may contain any additional data that should be included in the info, eg the `x-logo` and `x-tagGroups` extensions:
```elixir
spec = %OpenApi{
info: %Info{
title: "Test",
version: "1.0.0",
extensions: %{
"x-logo" => %{
"url" => "https://example.com/logo.png",
"backgroundColor" => "#FFFFFF",
"altText" => "Example logo"
}
}
},
extensions: %{
"x-tagGroups" => [
%{
"name" => "Methods",
"tags" => [
"Search",
"Fetch",
"Delete"
]
}
]
},
paths: %{ ... }
}
```
- Deprecation: `OpenApiSpex.Server.from_endpoint/2` has been deprecated in favor of `OpenApiSpex.Server.from_endpoint/1`.
Simply remove the `otp_app:` option from the call to use the new function. (#116)
```elixir
# server = Server.from_endpoint(Endpoint, otp_app: :my_phoenix_app)
server = Server.from_endpoint(MyPhoenixAppWeb.Endpoint)
```
- Fix: The internal representation of a Phoenix Route struct changed in Phoenix 1.4.7 breaking the `OpenApiSpex.Paths.from_router/1` function. OpenApiSpex 3.4.0 will support both representations until the Phoenix API becomes stable. (#118)
## v3.3.0 - 2019-05-05

* Feature: Enums expressed as atoms or atom-keyed maps can be cast from strings (or string-keyed maps). (#60) (#101)
Example:
```elixir
parameters: [
Operation.parameter(:sort, :query, :string, "sort direction", enum: [:asc, :desc])
],
```
- Fix: Schema module references are resolved in in-line parameter/response schemas. (#77) (#105)
Example: The response schema is given in-line as an array, but items are resolved from the `User` module.
```elixir
responses: %{
200 => Operation.response(
"User array",
"application/json",
%Schema{
type: :array,
items: MyApp.Schemas.User
}
)
}
```
- Fix: Ensure integer query parameters are validated correctly after conversion from string. (#106)
- Fix: Ensure integers are validated correctly against schema `minimum`, `maximum`, `exlcusiveMinimum` and `exclusiveMaximum` attributes. (#97)
- Fix: Ensure strings are cast to `Date` or `DateTime` types when the schema format is `:date` or `:date-time`. (#90) (#94)
- Docs: The contract for module supplied to the `PutApiSpec` plug is now documented by the `OpenApi` behaviour. (#73) (#103)
- Docs: Poison replaced with Jason in example and tests (#104)
- Docs: Improved documentation for combined `CastAndValidate` plug. (#91)
- Internals: Cache mapping from phoenix controller/action to OpenApi operation. (#102)
## v3.2.1 - 2019-03-11

## v3.0.0 - 2018-10-25
Major version bump as the behaviour of `OpenApiSpex.Plug.Cast` has changed (#39).
To enable requests that contain a body as well as path or query params, the result of casting the
request body is now placed in the `Conn.body_params` field, instead of the combined `Conn.params` field.
This requires changing code such as Phoenix controller actions to from
```elixir
def create(conn, %UserRequest{user: %User{name: name, email: email}}) do
```
to
```elixir
def create(conn = %{body_params: %UserRequest{user: %User{name: name, email: email}}}, params) do
```
- Feature: A custom plug may be provided to render errors (#46)
- Fix compiler warnings and improve CI process (#53)
- Fix: Support casting GET requests without Content-Type header (#50, #49)
- Open API Spex has been moved to the new `open-api-spex` Github organisation
## v2.3.1 - 2018-09-09
- Docs: Update example application to include swagger generate mix task (#41)
- Fix: Ignore charset in content-type header when looking up schema by content type. (#45)

## v2.3.0 - 2018-08-05
- Feature: Validate string enum types. (#33)
- Feature: Detect and report missing API spec in `OpenApiSpex.Plug.Cast` (#37)

## v2.2.0 - 2018-07-07
- Feature: Support composite schemas in `OpenApiSpex.schema`
structs defined with `OpenApiSpex.schema` will include all properties defined in schemas
listed in `allOf`. See the `OpenApiSpex.Schema` docs for some examples.
- Feature: Support composite and polymorphic schemas with `OpenApiSpex.cast/3`.
- `discriminator` is used to cast polymorphic shemas to a more specific schema.
- `allOf` will cast all properties in each included schema
- `oneOf` / `anyOf` will attempt to use each schema until a successful cast is made
## v2.1.1 - 2018-06-12
- Fix: (#24, #25) Operations that define `parameters` and a `requestBody` schema can be validated.
## v2.1.0 - 2018-06-08
- Feature: (#16) Error response from `OpenApiSpex.cast` when value contains unknown properties and schema declares `additionalProperties: false`.
- Feature: (#20) Update swagger-ui to version 3.17.0.
- Fix: (#17, #21, #22) Update typespecs for struct types.
## v2.0.0 - 2018-06-06
Major version update following from API change in `OpenApiSpex.cast` and `OpenApiSpex.validate`.
When casting/validating all parameters against an `OpenApiSpex.Operation`, the complete `Plug.Conn` struct must now be passed, where the combined params map was previously accepted.
This allows `OpenApiSpex.cast` / `OpenApiSpex.validate` to check that the parameters are being supplied in the expected location (query, path, body, header, cookie).
In version 2.0.0, only unexpected query parameters will cause a 422 response from `OpenApiSpex.Plug.Cast`, this may be extended in future versions to detect more invalid requests.
